Grips for any Handtool

Protective, Colorful Sleeves

Automotive Applications

Hot dip coating of plastisol
is a common method of applying a protective, decorative, or
functional plastic vinyl coating on a variety of metal parts.
Typical applications provide a protective layer against sharp or
rough materials, a protective plastic layer to prevent
corrosion, or just a beautiful and soft coating to enhance
the product's appearance.

It is much more cost effective to do a one step dip to coat a
product, for instance a tool grip, than it is to injection mold a
sleeve and then apply it to the handle. The coated grip is softer, has no seam lines, and adheres better to the
product to be coated. Applications for dip coating are
extensive and include:
• Hand tools
• Toys
• Medical Instruments
• Electrical Equipment
• Plumbing Fittings

Completing your plastic dip coating project is a straight-forward and comprehensive process. We work with you throughout the
production cycle to ensure the final product meets your design and material specifications.

1. Provide the coating specifications and material
properties; i.e., color, durometer, and thickness.
2. We submit a quote for your acceptance
3. You provide samples of the product to be coated.
4. We test dip coat the product and provide finished samples to spec
5. Upon approval, you ship the product to be coated to us.
6. Proceed to full production

1. Part Cleaning

Parts to be coated should be chemically cleaned to
remove contaminants . This results in superior
primer adhesion as well as improved corrosion
resistance.

2. Part Priming

If adhesion to the part is desired, application of
a primer is required on all sections were
polymer coating will be applied. The primed part
is flash dried and baked to set the primer and ready
the part for the hot dipping operation.

3. Part Dipping

The primed part, hot from the primer conversion bake, is immersed in the liquid
plastic polymer. All hot parts of the product immersed in the liquid
polymer will coat
upon withdrawal from the bath with a layer of semi-fused plastic. The
amount deposited will depend on the length of time the part was immersed, the
metal temperature that the part was immersed at, and the general formulation of
the plastic compound used. The higher the metal temperature, the longer the immersion
time, and the greater the film thickness.

4. Fusion (Curing) plastic polymer

The part covered with the semi-fused polymer is baked to a temperature between 300°F
and 350°F, depending upon the specific plastic compound formula.
This completes the fusion of the coating, and adhesion
to the product.

5. Cooling the Coated Part

When the hot part coated with fused polymer comes out of the oven, it is very sensitive to surface
marring. The part is cooled down in a tank of circulating cool water to a maximum of 120°F before handling.

6. Complete end product

The finished coated product is then removed from the
conveyors and readied for packing and shipment.
